1.4 Roll Paper Supply Unit
1) Supply method: Drop-in roll paper
2) End sensor
a) Detection method: Mechanical microswitch
b) Detection position: Positioned within the paper path for the roll paper; detects a
paper-end.
3) Roll paper near-end sensor: Installed in the case unit (factory option)
a) Detection method: Mechanical microswitch
b) Inner diameter of the roll paper core:
10.5 to 12.5 mm (See APPENDIX B for details.)
NOTE: The standard model of this printer is not equipped with a mechanism that detects the amount
of roll paper remaining (a roll paper near-end sensor). Roll paper may jam if the roll paper
core and paper are attached to each other by tape or glue. Because of this, be sure the
printer detects the amount of roll paper remaining with the optional roll paper near-end
sensor when the paper is attached to the core by tape or glue, or exchange the roll paper
with a new one before the current roll paper is finished by checking the end mark.
